Turns out it was an out dated certificate in

    < profile>.android/debug.keystore

Delete the key, and re-launch on the android device

I deleted the file, but still have the same error while compiling from Git source

I finally fixed it by doing the follow step:

  1. redo git checkout branch 4.9
  2. delete Intermediate & DerivedDataCache folder
  3. Uninstall UnrealVS extension for VS2013
  4. re-run setup.bat / generateprojectfile.bat
  5. now successfully build Android/Development.

thanks ~~~ Have no idea which step fixed it.
